Botanicare ProGro MP4 Mix Mycorrhizae high porosity growing media
ProGro MP4 Mix is a high porosity substrate built from carefully screened peat materials—fine particles that block pores and reduce airspace are rejected to maintain better structure. This helps improve water availability while supporting consistent oxygen flow through the root zone. Use it to set plants up for steadier growth and easier moisture management in containers.
Mycorrhizae-enhanced mix for greenhouse drip irrigation
This mycorrhizae-enhanced peat-based mix is ideal for greenhouse drip irrigation with frequent watering cycles and repeatable fertigation routines. It also performs well for perennials and annuals including vegetables, hanging baskets, and potted flowers. For best results, expand the compressed material, moisten before planting, gently compact to reduce settling, then water in and fertilize as needed according to your nutrient label.
